CC -!- FUNCTION: Exchanges the guanine residue with 7-cyano-7-deazaguanine
CC (preQ0) at position 15 in the dihydrouridine loop (D-loop) of archaeal
CC tRNAs. {ECO:0000256|HAMAP-Rule:MF_01634}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=7-cyano-7-deazaguanine + guanosine(15) in tRNA = 7-cyano-7-
CC carbaguanosine(15) in tRNA + guanine; Xref=Rhea:RHEA:43164,
CC Rhea:RHEA-COMP:10371, Rhea:RHEA-COMP:10372, ChEBI:CHEBI:16235,
CC ChEBI:CHEBI:45075, ChEBI:CHEBI:74269, ChEBI:CHEBI:82850; EC=2.4.2.48;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01634};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01634};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01634};
CC -!- PATHWAY: tRNA modification; archaeosine-tRNA biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_01634}.
CC -!- SIMILARITY: Belongs to the archaeosine tRNA-ribosyltransferase family.
CC {ECO:0000256|HAMAP-Rule:MF_01634}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01634}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
